Public Member Functions
	QGraphicsSceneResizeEvent ()
	Constructs a QGraphicsSceneResizeEvent.
	~QGraphicsSceneResizeEvent ()
	Destroys the QGraphicsSceneResizeEvent.
QSizeF	oldSize () const
	Returns the old size (i.e., the size immediately before the widget was resized).
void	setOldSize (const QSizeF &size)
QSizeF	newSize () const
	Returns the new size (i.e., the current size).
void	setNewSize (const QSizeF &size)
Public Member Functions inherited from QGraphicsSceneEvent
	QGraphicsSceneEvent (Type type)
	~QGraphicsSceneEvent ()
	Destroys the event.
QWidget *	widget () const
	Returns the widget where the event originated, or \nullptr if the event originates from another application.
void	setWidget (QWidget *widget)
quint64	timestamp () const
void	setTimestamp (quint64 ts)
Public Member Functions inherited from QEvent
	QEvent (Type type)
	Constructs an event object of type type.
virtual	~QEvent ()
	Destroys the event.
Type	type () const
	Returns the event type.
bool	spontaneous () const
	Returns true if the event originated outside the application (a system event); otherwise returns false.
virtual void	setAccepted (bool accepted)
bool	isAccepted () const
void	accept ()
	Sets the accept flag of the event object, the equivalent of calling setAccepted(true).
void	ignore ()
	Clears the accept flag parameter of the event object, the equivalent of calling setAccepted(false).
bool	isInputEvent () const noexcept
bool	isPointerEvent () const noexcept
bool	isSinglePointEvent () const noexcept
virtual QEvent *	clone () const
	Creates and returns an identical copy of this event.

Detailed Description

The QGraphicsSceneResizeEvent class provides events for widget resizing in the graphics view framework.

Since

4.4

\inmodule QtWidgets

A QGraphicsWidget sends itself a QGraphicsSceneResizeEvent immediately when its geometry changes.

It's similar to QResizeEvent, but its sizes, oldSize() and newSize(), use QSizeF instead of QSize.
